Outline of Final Research Achievements

The authors developed the new acoustic survey system to investigate shallow water areas, and then investigated landslides that occurs in coastal and shallow water areas to study the relationships between those landslides and tsunami hazards. The new survey system consists of unmanned watercraft and sonars, has the high resolution sonar imaging and the side-scan sonar imaging feature, in addition, is easy to introduce small and shallow water areas. The watercraft has remotely control system, and the operator can receive the real-time position of it. By using this system, the authors realized to make bathymetry and to analyze surficial geology with low-cost. The authors investigated five water areas and found a number of landslide topography and geologic structures.
